Rare Veteran Vintage 6HP JAP V Twin Engine Rover Brough Sunbeam Coventry Eagle
Item History & Price
| Reference Number: Avaluer:518394 | Brand: Sunbeam |
This auction is for an extremely rare 654 cc JAP V twin engine which was fitted to many other quality machines from the veteran and early vintage era. The engine number (H53843) denotes it as being originally fitted to a Rover V twin built for the Russian army in WW1 but never delivered due to the revolution and then sold onto the civilian market. An article in The Motor Cycle on April 5th 1917 announced the model (thanks to 'Yesterdays' of Holland for this information). There are also... various other stamps including the number '14' in a circle which may denote the year of manufacture, another saying 'JAP PATENT' as well as the number '904' stamped into each crankcase half which shows the halves are matched and left the factory together. There are a couple of other random letters which appeared after cleaning which I can't see mean anything and perhaps they were part of the manufacturing process.
I've had the cast aluminium parts very gently aqua blasted by a specialist experienced in working on old bikes to clean them as they were filthy. I forgot to take the magneto chain cover so this will need cleaning. The barrels have been bead blasted to clean them and I've left the pistons and conrods alone to be inspected and cleaned by the new owner. The conrods have surface rust but the big end seems to be good - moving smoothly with no play. However I'd recommend a strip and inspection at the minimum. There are some parts missing as you will see such as one cam, a cam-wheel and timing cover but the main parts are there including the crankcases, crankshaft, con rods which are in good condition with no play, pistons and rings (no gudgeon pins), barrels with good bores, valves, springs and collets, one camshaft, a set of followers and guides etc.
The engine looks to be in good condition and I've loosely assembled it to see what's there. Unfortunately I forgot the conrods when I put it together so they appear in a separate photo! The engine appears to have been stored for a long time and as such the barrels have no broken or missing fins apart from one small nibble in one fin which can be seen in the photo's and there is no significant corrosion to the crankcases.
The winning bidder is very welcome to collect and have a cup of tea but I'm also happy to send to the UK and abroad. In the UK I will send this insured via a good quality courier such as UPS or Parcelforce, it's too valuable and historically significant to send via Hermes. Insurance costs can be up to 5% of the value and I will need to add this to the shipping cost. If you'r rather take the risk of having no insurance please let me know but in this case I cannot be held responsible for loss or damage. If the buyer is reasonably close I will deliver to ensure it arrives safely.If bidding from abroad I will also use a decent insured courier service but please bear in mind the cost of shipping as this is pretty heavy. I will also need to send this insured which will cost of up to 5% of the value which will be on top of the shipping cost. Please ask for a shipping quote for your location if bidding from overseas.I can also, work permitting take this to Founders Day in July if the winner would prefer that.Please take no notice of the international shipping price as shipping costs vary according to your location.I do not sell to Africa, Asia (apart from Japan) or Russia/CIS without prior arrangement. Please do not bid if you have less than 10 positive feedbacks without contacting me first. Sorry for these rules but I've been caught too many times including recently when someone from India bid despite me saying I won’t sell there. I cancelled the bid and the ‘winner’ then tried claiming a refund for a payment they never made. What a surprise! The ebay helpline then showed me how I can get a list of every country in the world and select which ones I won’t sell to and applied it to all future sales. Hopefully that’ll be an end to it.Happy Bidding!
